The TC7MP245FK(EL) is a high-speed, low-voltage 8-bit dual supply bus transceiver manufactured by Toshiba Semiconductor and Storage. This device is designed for asynchronous communication between two systems where differing voltage levels are present. The dual supply feature allows for independent voltage levels on the A and B ports.

Applications:

• Level Translation: Used to interface between different voltage domains in mixed-voltage systems.
• Bus Isolation: Isolates sections of a bus system to prevent signal interference.
• Data Acquisition Systems: Employed for transmitting data between ADCs/DACs and digital signal processors.
• Memory Interfacing: Used in memory systems to buffer and control data signals.
• Communication Systems: Suitable for bidirectional data transfer in various communication applications.

Features:

• Dual Supply Operation: Operates with two independent power supplies (VCCA and VCCB) allowing for level translation.
• High-Speed Operation: Provides fast data transfer rates, enhancing system performance.
• Low-Voltage Operation: Operates at low voltage levels, reducing power consumption.
• Bidirectional Data Transfer: Allows data to flow in both directions, offering design flexibility.
• 8-Bit Bus Transceiver: Handles 8 bits of data simultaneously.
• Tri-State Outputs: Feature tri-state outputs, enabling multiple devices to share the same bus.

Benefits:

• Improved System Compatibility: Simplifies integration of devices with different voltage requirements.
• Reduced Power Consumption: Low-voltage operation minimizes power consumption, extending battery life.
• Enhanced Design Flexibility: Dual supply and bidirectional data transfer offer greater flexibility.
• Simplified Bus Interface: Simplifies the interface between buses operating at different voltage levels.
• Increased System Performance: High-speed operation ensures efficient data transfer.

Additional Details:

The TC7MP245FK(EL) offers separate VCCA and VCCB supply pins, enabling voltage level translation. The direction control (DIR) input determines the direction of data flow between the A and B ports. The output enable (OE) input controls the output state, allowing the outputs to be disabled for bus isolation. The device is designed to meet industry-standard specifications for EMC and ESD protection. It is available in a small fine pitch package to save board space. The device is suitable for operating temperatures ranging from -40°C to +85°C. Its dual supply capability makes it suitable for applications that require level shifting, such as connecting a 1.8V microcontroller to a 3.3V peripheral device. The 'EL' suffix denotes that the component is lead free and RoHS compliant.
